JOSEPH ASPINALL, OF BOLTON, ENGLAND.

SPECIFICATION forming part of Letters Patent No. '758,496, dated April 26, 1904.

Application filed May 29, 1903. Serial No. l59,2'70. (No inodel.)

To all whom it may concern:

Be it known that I, J OSEPH ASPINALL, agent, a subject of the King of Great Britain and Ireland, residing at 27" Park View road Daubhill, Bolton, in the county of Lancaster, England, haveinvented new and useful Improvements in Rope or Cable Grips for Haulage Purposes, of which the following is a specification.

This invention relates to improvements in rope or cable grips for haulage purposes, and is more particularly intended for use in the under haulage of tubs in coal and other mines, though it may also be applied for other haulage purposes where there is a more or less continuously running or traveling rope or cable, the object of the invention being to provide a gripping device that can be used either for pulling or pushing the tubs, as occasion may require, and at the same time one which can be -readily attached to or released from either the cable or rope or the vehicle containing. the load to b e carried.

My invention consists, essentially, in an open sided jaw forming one portion of the grip, carrying therein a looseor pivoted jaw which can be forced into contact with the rope or cable by means of a pivoted lever provided with arms or a cam-shaped surface designed to come in contact with the loose or pivoted jaw, whether the lever is pulled 'or pushed in one direction or the other, the said lever being connected to the load-carrying vehicle either directly or by means of a link, rope, chain, or the like.

My invention will 'be fully described with reference to the accompanying drawings, in which- Figure l is a side elevation of the grip; Fig. 2, a sectional elevation on line 1 2 of Fig. 1; Fig. 3, aside elevation, partly in section; and Fig. 4 a plan on line 3 4 of Fig. 3. 4

In' carrying out my' invention I provide an open-sided jaw a of 'a size sufiiciently strong to suit the loadto be pulled or pushed 'and made of any material suitable for the purpose. One portion of the jaw is constructed to embrace the haulage cable or rope b, and extendpreferably chambered in such a way as to hold therein a loose or movable jaw d, designed to be capable of being moved toward or from the cable. The jaw may be entirely loose in the chamber or it may be provided with'slots or slotted arms e at either side, the said arms being formed integral with the jaw or, as indicated in the drawings, merely consist of plates pivoted or 'riveted or otherwise Secured to the jaw d at d'. f' represents the slots which embrace a pin g, passed through the main portion of the jaW d and riveted thereto or loosely Secured therein. The slotsf act somewhat'as a ,guide during the movement of the jaw from the full-line position to the broken-line posi tion, (indicated in Fig. 3,) in which latter position the jaw securely grips the cable between itself and the main portion or jaw a. In order to move the jaw d toward the cableb, I i

pivot on the pin g a lever h, provided at that end nearest to the loose or pivoted jaw d with projecting arms i or a cam-shaped surface or surfaces, While the other end of the lever may be connected to the load-carrying vehicle dii rectly or by means of a link or hook j, rope,

chain, or the like. As an additional means of guiding the jaw d during its movement I may form on the jaw projections Ic, as indicated in Fig. L.

A gripping device such as I have described is especially suitable for underhaulage in connection with coal or other mines, no matter whether the roads or ways are inclined, level, or undulating, as the loaditself is the medium by which the loose jaw is caused to approach and grip the cable between itself and the embracing portion of' the gripping device, and the latter is of such a character that the load can either be pulled or pushed. At the same time the device can be readily disconnected when required. To increase the effectiveness of the grip, the surfaces of the jaws coming in contact With the cable may be roughened, if desired. I

What I claim as my invention, and desire to protect' by Letters Patent, is-

1. A rope or cable grip for haulage purposes comprising an open-sided jaw forming one portion of the grip, a chamber at the lower part of said jaw, having located therein a jaw normally resting on the bottom of the chamber, a pivoted lever in contact With the loose jaw provided at one end With two arms for Operating the loose jaw and at the other end With a hook substantially as and for the purposes described.

2. A rope or cable grip 'or haulage purposes comprising in combination an open-sided jaw, a loose jaw arranged in achamber therein, a pivoted lever provided With arms designed to come in contact With the loose jaw, slotted arms attached to the loose jaw and a connecting-hook attached to the lever for operating the loose jaW substantially as described.

3. A 'ope or cable grip for haulage purposes comprising an open-sided jaw forming one portion of the grip, a chamber at the lower part of said jaw having located therein a jaw normally resting on the bottom of the chamber, slotted arms formed on the loose jaw embracing a pin passed through the lower portion of the open-sided jaw, guiding -pieces formed on the loose jaw on either side of the pin and a pivoted lever in contact 'With the loose jaw provided at one end with two arms for Operating the loose jaw and at the other end With a hook substantially as and for the purposes described.

4. A rope or cable grip for haulage purposes comprsng an open-sided jaw 'orming one portion of the grip, a chamber at the lower part of said jaw having located therein a jaw normally resting on the bottom of the chamber, a pvoted lever in contact With the loose jaW provided at one end With a cam-shaped surface for Operating the loose jaw and at the other end With a hook substantially as and for the purposes described.

In Witness whereof I have hereunto set my hand in the presence of two witnesses.
